The Role of Water Content of Deep Eutectic Solvent Ethaline in the Anodic Process of Gold Electrode

Molecules, 2023
Traditional coupling of ligands for gold wet etching makes large-scale applications problematic. Deep eutectic solvents (DESs) are a new class of environment-friendly solvents, which could possibly overcome the shortcomings.

Silicon recovery from silicon-iron alloys by electrorefining in molten fluorides [PDF]

, 2013
Electrorefining of a silicon-iron material (Si-4.7at%Fe) in molten NaF-KF at 850°C has been investigated in view of recovering pure Si, using electrochemical techniques, SEM-EDS and ICP-AES analyses.

Anodic behaviour of Cu, Zr and Cu–Zr alloy in molten LiCl–KCl eutectic [PDF]

Royal Society Open Science, 2019
The anodic dissolution behaviours of Cu, Zr and Cu–Zr alloy were analysed in LiCl–KCl at 500°C by anode polarization curve and potentiostatic polarization curve. The results show that the initial and fast-dissolving potentials of Cu are −0.50 and −0.29 V,

An electrochemical investigation of the formation of CoSx and its effect on the anodic dissolution of iron in ammoniacal-carbonate solutions [PDF]

, 2013
It has been found that the co-presence of cobalt (II) and thiosulphate ions in ammoniacal-carbonate solutions promotes the passivation of iron, under conditions in which it would otherwise continue to dissolve anodically. Electrochemical experiments have
